Is the ordered pair (0,5) a solution of the system of linear equations:

Recall that an ordered pair is a solution of a system of linear equations if it satisfies each equation.
Notice that:
[tex]0+5=5.[/tex]Also, notice that:
[tex]-5\cdot0+2\cdot5=0+10=10.[/tex]Therefore the ordered pair (0,5) satisfies the given system of equations.
Answer: Yes.
